Description
The Adams Rite 4510 Series Mortise Deadlatch provides flexible traffic control for hospitals, banks, and commercial buildings that require free entrance during business hours and exit-only access at other times. The reverse-turn key mechanism holds the bolt retracted for two-way traffic without stile modification, making it ideal for high-security applications demanding adaptable access policies.
This lock is interchangeable with MS1850A or MS1850S deadbolts of matching backset and faceplate shape. The steel case with corrosion-resistant plating and hardened steel internal pins ensures durability. Available in four cylinder backsets: 7/8", 31/32", 1-1/8", or 1-1/2". Handing is reversible without special tools. For proper sizing, backset selection, and cylinder compatibility, contact our authorized dealer experts at sales@edlocks.com or 1-877-207-6067.
